A/T - Oil Leakage at Dipstick Vent

SIL 86-21 (Sept)

SUBJECT: 1978-1983 CHRYSLER TRANSAXLE

SYMPTOM/CONDITION:
Oil leakage at dipstick vent.

DIAGNOSIS:
Inspect for presence of fluid at the dipstick handle.

PARTS REQUIRED:

1 Dipstick Assembly P/N 4348625 (1978-83 Models w/c Common Sump)

1 Dipstick Assembly P/N 42959117 (1983 Models with Common Sump)

REPAIR PROCEDURE:

The dipstick assembly on front wheel drive automatic transaxles is of a hollow tube-type design. The hollow handle allows air to be vented into and out of the transaxle as needed due to temperature changes.

The dipstick handle is the only air vent on 1983 transaxles (common sump with the differential) and should never be plugged. Plugging the vent could result in either oil being forced past the external seals, or the dipstick popping out of the transaxle, resulting in leak complaints.

If oil is "leaking" out of the dipstick handle (vent), the usual cause is either too much oil in the transaxle and/or long-term (2-3 days) downhill parking on a steep incline (either on road surface or during vehicle shipment).

Oil level must be verified at normal operating temperature (refer to service manual). A revised dipstick with a higher venting point to help reduce oil leakage at the dipstick is available. Install the dipstick as indicated in the above "Parts Required" section.
